If your engine was designed before 1989, the camshaft's non-roller lifters require ZDDP in the motor oil to prevent premature deterioration. However, the U.S. government recommended that ZDDP no longer be put into domestic motor oils starting in 1989, so today's motor oils won't provide the ZDDP additive your older engine needs...unless you add this ZDDP Oil Additive!

About Eastwood ZDDP Oil Additive 4 oz.

After 70+ years, the EPA mandated that all oil domestic producers remove ZDDP (Zinc Dialkyl Dithio Phosphate) from all conventional and synthetic motor oils. If your engine was designed before 1989 the non-roller lifters require ZDDP to avoid premature deterioriation. ZDDP also alters bearing and journal surface characteristics to prevent metal to metal contact. Under extereme conditions like a high perfromance motor, ZDDP reduces the tendancy of parts to scuff or gall under heavy loads. Simply add Eastwood ZDDP Oil Additive to every 4-6 quart oil change and your motor will be protected.
